Cascade reservoir control system and method for breeding demand of viscosity production demersal fish

Abstract

The invention discloses a cascade reservoir control system for breeding demand of viscosity production demersal fish. The cascade reservoir control system comprises a water temperature and weather intelligent monitoring platform, a system running support platform and a cascade reservoir ecological dispatching decision platform, wherein the water temperature and weather intelligent monitoring platform comprises a water temperature monitoring unit, a data receiving base station, a power station monitoring center and a system monitoring center, the system running support platform comprises a communication transmission system and a network system, and the cascade reservoir ecological dispatching decision platform comprises a dispatching information layer, a dispatching decision layer and a dispatching operation layer. A control method disclosed by the invention is used for controlling according to the control system. The control system is used in a breeding period of the viscosity production demersal fish, a coordinative control technology of an upstream reservoir matched with running of a stoplog gate to control a water temperature and a last-stage reservoir to regulate flow quantity is used for providing a moderate water temperature and flow quantity condition for breeding of the viscosity production demersal fish, and the influence of the running of the cascade reservoir on the breeding of the viscosity production demersal fish can be reduced.

Description

technical field [0001] The invention relates to the technical field of ecological control of water conservancy and hydropower projects, in particular to a cascaded reservoir control system and method for the reproduction needs of fishes that produce viscous eggs. Background technique [0002] my country's water conservancy projects have developed rapidly. World-class hydropower project groups have begun to take shape in hydropower bases such as the Jinsha River, Yalong River, Dadu River, Wujiang River, Nanpan River, and Lancang River. While exerting great benefits in such aspects as river biological resources and their living environment, it also brings adverse effects. After the reservoir was impounded, a huge stagnant water area was formed in the reservoir area. On the one hand, the natural runoff process of the river was changed, which changed the hydrodynamic environment of the downstream channel. Under the influence of solar radiation and convective mixing and heat tran...

Problems solved by technology

The above-mentioned ecological regulation methods are all aimed at the demand for hydrodynamic conditions for the reproduction of specific fishes, and have not considered the requirements for the water temperature structure for the reproduction of target fishes, and these ecological regulation methods are all for a single reservoir; It can flexibly control the discharge water temperature and is widely used in large-scale water conservancy and hydropower projects. However, due to the height limit of a single-section logger door, the submerged water depth at the top of the logger door varies greatly, and the effect of the logger door is limited when taking the surface water of the reservoir; , when carrying out ecological control, the combined use of engineering measures is not considered enough, and there is still a gap in the coordinated use of engineering measures and non-engineering measures
